NOVELTY - Preparing graphene comprises adding a nano-small molecule aqueous solution to graphite under ultrasonic high-frequency oscillation. The nano-small molecule aqueous solution is intercalated between the expanded graphite layers, and then centrifuged to obtain precipitation. The precipitation is fed into a high-temperature kettle of 400-600degrees Celsius, where the intercalated solution rapidly gasifies and expands rapidly in volume. The expanded graphite is directly delaminated, where the product collected at the outlet is graphene. USE - Method for preparing graphene for preparing washing and protecting articles selected from soap, washing powder, laundry liquid, shampoo, facial cleanser, body lotion, and conditioner (all claimed). ADVANTAGE - The method prepares the graphene in a simple manner, which removes oil on the skin, near the hair follicle of the hair root and on the hair, and has a deep cleansing effect on the skin, and guides skin regeneration.
